Your high school Math(s) teacher might not even explain to you how Heron's formula is derived, let alone Heron's original idea. This video explains 4 different ways to prove the Heron's formula. • Note: • This is a sort of experiment for longer videos. I am not exactly sure whether this would be helpful for both you and me, but let's see. • Sources: • https://manuscriptsandmore.liverpool....
